QUICK START
GUIDE
Connecting a Signal Ground
(common, reference) on the RS-422/485 side.
The specifications for most RS-422 and RS-485
devices indicate that the device can withstand a
maximum VCM of -7 Volts to +12 Volts. The function of
the GND connection is to tie the signal grounds of all
nodes on a network to one common ground potential.
This ensures that the common mode voltage cannot
exceed the specified value.
A signal ground is required on Model BB-485DRCI-
PH because it is an optically isolated device. If you do
not have a signal ground (common, reference) on your
RS-422/485 device, you can connect to the DC power
ground of your RS422/485 device.
Caution: Make sure that this is connected correctly.
Note: Do Not use the shield drain wire as the signal
ground between RS-422/485 devices.
